I've got 86 cents worth of silver left in my CN account, which you can have for free since I don't like carrying loose change around. This should cover your tax for about 10 months and change, and don't ever say I didn't do anything for you.
I too got my money's worth with R+. I did not get the M+ either. If Sprint had not pulled the plug on Karl I would probably be using the smart dialer today. Until they shut down, the only complaint I had with R+ was the delay which was fixed with the mad plans.
